Issue ID

UUM-107379

Regression

Yes

SpriteShapes are rendered using multiple draw calls when the SRP Batcher determines their nodes are incompatible in a specific project

-

How to reproduce:
1. Open the attached “IN-99330” project
2. Open the Frame Debugger window (Window → Analysis → Frame Debugger)
3. In the Frame Debugger press the “Enable” button
4. In the Frame Debugger Event Hierarchy expand the “(RP 0:0) Renderer2D Pass” event (“UniversalRenderPipeline.RenderSingleCamera” → “(RP 0:0) Renderer2D Pass”)
5. Observe the expanded “(RP 0:0) Renderer2D Pass” event

Expected result: “(RP 0:0) Renderer2D Pass” contains “RenderLoop.DrawSRPBatcher”
Actual result: “(RP 0:0) Renderer2D Pass” contains “RenderLoop.Draw”

Reproducible with: 2022.3.61f1, 6000.0.41f1, 6000.0.49f1, 6000.1.3f1, 6000.2.0b1
Not reproducible with: 6000.0.40f1

Reproduced on: Windows 11, macOS 15.3.2 (Sequoia) (User)
Not reproduced on: No other environment tested

Note: The first “Draw Mesh” call in the “RenderLoop.DrawSRPBatcher” displays “SRP: Node is not compatible with SRP batcher” in the event details

  1. Resolution Note:

    To ensure SpriteShape can utilize SRP-Batcher, all Edge Sprites including Corner Sprites should be part of the same Texture in SpriteAtlas or a SpriteSheet.
    In the given project, even though sprites are part of SpriteAtlas, there are two textures created due to not being able to fit all Sprites to a single Texture. This can be fixed easily either by
    1. Increasing Max Texture Size of SpriteAtlas.
    2. Removing Fill Texture from the SpriteAtlas as Fill texture does not need to be a Sprite and hence can be removed from the SpriteAtlas.
    This should fix the issue. Previously in certain versions SpriteShape was incorrectly enabling SRP-Batcher even if multiple textures were used. This has been fixed recently.
